Bought a Beam on Black Friday, noticed a bit of delay, tweaked it using the TV/Sonos app settings and it's all good now :)
Unless you mean that it drifts over time? Because I've not noticed that, and if it does/I do, I'll never forgive you
I don't know about drift but it usually happens when there is DD going on. Which means that if you adjust for it, when you get stereo you have to adjust back. Which is annoying.
I was drunk when I made this thread, so sorry about the aggressive tone lol. I am interested in other people's experiences here though because I can't understand how people are not getting lag.
I first noticed this when I had a playbar some five years ago or more. At that time I had a Samsung 1080p 3D TV, I can't remember the model number but it was at the high end of the market. I didn't notice lag through my consoles at that time, nor through Smart TV apps but on my Sky box it was maddening. Whatever I set the audio delay to, it would need adjusting according to which channel I was watching (though I now think this was due to some being presented in stereo and some in DD). And once I noticed it, it became an obsession. I would always look out for it and I would often find it. In the end I just learned to live with it.
Last year I moved house and couldn't Sky so switched to Virgin and bought a new TV - a LG OLED 4K C7. Still with the playbar. Similar issues. Not exactly the same but at least as bad if not worse with the virgin box and now also with the PS4 as a bluray player.
Around this time I bought one Sonos One. Then another one for pairing.
I then renovated another room to use as another living room. Bought a new TV - a Phillips 7304 4K LED I got on sale. This is a cheaper TV. I considered buying a 'proper' home theatre system this time but I was spending so much money on renovations and I already had the two Sonos Ones I just thought 'fuck it' and bought a Beam. Yet again similar lag issues through Virgin and Blurays through my Xbox are absolutely horrendous. The only way I could fix that was to intentionally lag the picture by adding in all that IQ correction shit you're supposed to turn off. Which did alleviate the problem somewhat but not completely.
Until the other day when I decided to try taking the optical out of my TV and run iut directly to the Xbox. Boom problem solved.
I have no idea why I didn't try this before. I guess I didn't want even more cables. But now I have optical cables running from my TV, Xbox and Virgin box to a splitter to the Beam and everything is in sync.
So that's three TVs. three manufacturers, all with HDMI passthrough, all with lipsync issues. So I think it must be a pretty big problem. But all these people say they've never noticed it. I'm not sure if it's really not a problem for them or they just don't notice it. My wife has never noticed it either. She doesn't know what the fuck I'm talking about lol.
If you don't notice it, I guess the best thing to do is close this thread and never think about it again because if you look for it and find it, you'll never be able to not notice it again.
One thing to check, if you have your sound set to PCM on your output device, everything works fine. But PCM won't play in surround sound with HDMI passthrough. ARC will only process stereo. It sounds like shit compared to DD. Check your Sonos app to see if you are getting 5.1, you won't get it if your device is set to PCM
